- Pharmacodynamics
Talbutal is a short to intermediate-acting barbiturate that is a nonselective central nervous system (CNS) depressant. As with other barbiturates, talbutal is capable of producing all levels of CNS mood alteration from excitation to mild sedation, hypnosis, and deep coma. Barbiturates may also induce anesthesia at sufficiently high therapeutic doses.
- Mechanism of action
Talbutal binds to GABAA receptors at a distinct binding site associated with a Cl- ionopore of the receptor. Upon binding, talbutal increases the duration of time for which the Cl- ionopore is open, leading to prolonged inhibitory effect of GABA at the postsynaptic thalamic neuron.
